To @ZZ whom t may concern.'

Be it known that PHILIP MUELLER and ANTON C. SCHUERMANN, citizens of theUnited States, residing at Decatur, in the county of Macon and State ofIllinois, have invented new and useful Improvements in Waste .Stoppersand Operating Mechanism, of which/the following is a specification.,

This invention relates Ato waste Stoppers for bowls, lavatories, andanalogous devices, and to an improved constructionin the operating:mechanism thereof. The present case is a division of application,Serial No. 337,496, filed Nov. 12, 1919, Patent No. 1,447,808, March 6,1923. y

Itis customary in wastefstopper constructions*A of this" type to'haveparts of the operating 'mechanism disposed within the stopper, whichnecessarily has a tendency to obstruct the. passage of wat-er andforeign material passing'through the stopper` and eventually cause theclogging or stopping up of the waste outlet. p y

In order to overcome these defects, the present development providesmeans arranged outside of the stopper, for actuating the same, so as topermit a free and unobstructed passageway through the waste outlet.

The present invention has further for its object an adjustable wasteiitting that is adapted for use with 'bowls of diiferent thickness, andbowls in which the waste outlet is positioned at different heightsrelative to the faucet or supply spout.

lA still further advantage of the'present construction resides inproviding an actuating mechanism in ,which the lifting rod is adapted togive a straight lift to the stopper without imparting any turningmovement to any'of the parts, thus dispensing with the complicatedconnections employed in, similar devices, wherein a 'rotary movementy isimpartedto'the stopper forlefl'fecting operation ofthe same.

' fIn the drawingsherewith illustrating embodiments of our invention, j

F'fgure 1 fs aview in centraljV vertical section of a bowl equipped witha waste xture made in"l accordance with 'our invention.'

Figure 2 is ahorizontall sectional view VVon substantially/'the line242ofr1igure 1,'show- ,ing thaw-aste Stopper-Tantas! actuatinjgriyoke.

Figure 3 is a detail view in vertical section on the line 3-3 of Figure2.

Referring to the drawings, wherein like numerals denote like parts inthe various views, 10 designates a wash bowl of any suitable material,design, and dimensions, and preferably composed of vitreous ware,although it is obvious that our invention is adapted to bowls ofy variedmaterial and construction..f Y

Thejbowl 10 is formed with the usual bowl slab 11, aback slab .12, andmay be pro; vided with an overflow'13 vleading to the waste outletarranged in the' bottom of said bowl. p 1

The'said waste outlet isprovided with a sleeve fitting. 14, passingthrough and below the bottom ofthe bowl, and formed `at its upper endwith anoutwardly extending shoulder 15, vwhich is adapted to abut thegasket 19 preferably arranged in theV recess in the bottom of the bowl10. The sleeve 14 extends an appreciable distance below the bowl r'andis externally threaded throughout the greater part of its length soYthat the'adjustable housing 16 and thepacking 17 may be effectively'secured to the bowl.

A hollow tubular stopper 18 is provided at-itsupper vendwith a conicalhead 18i adapted/to. abut aga-inst and be supported by a conical seat inthe end 'of thev sleeve 14. The stopper is further provided at its upperend with a plurality of slots 20 for permitstopper 18 is provided withdiametrically opposed grooves 23, and flat sides 24, as shown in Figures2 and 3, for a. purpose now Vto be set forth.v

' An actuating yoke 25'is adjustably mounted on a lifting rod26 passingthrough the housing- 163 {The arms 27 of saidyoke are normally arranged?to straddle the lower end ofthe waste stopperand iit within `the.

grooves 23, thus preventing the disengagearms 27 untilthe iiattene'dportions 24 are arranged infparallel alignment therewith,"Wherfllsetharsis stepper Ami' be readily Vment or'V removal 0fthestopper-from the withdrawn. The lifting rod 26 passes through astui'iing boX 27 formed in an ordsct portion otl the casing 16, and itsmovement is steadied by means of a guiding lug 28 formed in the interiorof the housing and through which the lower end of the said rod isadapted to pass.

A substantially L-shaped member 29 is adjustably connected to the rod 26by the pin 30, which is threadedly connected to the member 29. Anoperating rod 31 is similarly secured to the vertical portion of themember 29, and passes through and beyond the supply spoilt 32 so as toprovide at its upper end an operating knob or `handle '33 for actuatingthe waste stopper 18. .A tube 34 surrounds' the operating rod within thesupply spout and is threaded or otherwise secured at its upper extremitywithin the neck of the spout 32, and at its lower end to the securingnut 35.

With this arrangement it will be seen that a suitable range ofadjustment is provided to meet diiierent conditions arising through thevariations of the thickness ofV the bowls 10, or the positioning of thesupply spout 32 at different angles with respect to the waste stopper18. Furthermore, by arranging the arms 27 ot the fork 25 to exteriorlyembrace the stopper 18, an unobstructed passage is provided within thestopper so that water and foreign material may easily and VJfreely passtherethrough without danger of obstructing sediment and clogging up theoutf let.

j while a preferred embodiment of the same is merely lillustrative andin no sense restrictive, for the construction may be varied as tomechanical details without departing from the spirit of the inventionand the scoA e of what is claimed.

i' VVTe claim: Y

1. The combination in a fitti-ng of the class described, of a stopper,astopper casing into which the lower end of said stopper projects, avertically disposed liftingrod extending from said casing, a vertical-lyadjustable yoke on said rod and embracing said stoper. and Vmeans onsaid sto s er for lookin@r i b the Yparts together when the stopper isrotated in a predetermined position.

2, The combination a -iitting er the class described,o: t a stopper, astopper/easing into which the lower end of said stopper projects, avertically disposed lifting rod extending trom said casing, a verticallyadjustable yoke on said rod and embracing said stopper, means on saidstopper for locking the parts together when the stopper is rotated in apredeterinined position, and means in said casing for guiding the lowerend oi said lift-ing rod.

3. rl`he combination in a fitting ot the class described, of a stopperhaving a groovedl lower end and flattened opposite sides, a stoppercasing into which the lower end of said stopper projects, a lifter rodin said casing projecting eXteriorly thereof, a yoke adjustably mountedon said litter rod and engaging said grooved stopper, and means toprevent accidental rotation of said stopper and disengagement of saidyoke, said means being removable to permit the stopper to be rotated inthe yoke and withdrawn when the flattened sides are brought to apredetermined position.

d. The combination in a fitting of the class described, of an operatingyoke, and a stopper having a grooved lower end and flattened oppositesides to permit it to be engaged with or disengaged from 4said yoke.

5. The combination of a waste stopper, a stopper lifting yoke straddlingsaid stopper, and in rotatable relation thereto, and means on theperiphery of said stopper to lock the stopper and yoke for simultaneousreciprocating movement when rotatedA to `a predetermined angularrelation and to permit their independent movement and separation whenrotated to another angular relation.

6. The combination of a waste stopper having an interrupted groove inits outer wall, and a yoke straddling said stopper and engaging saidgroove tolock the parts together for simultaneous rec-iprocation in apredetermined angular relation, said stopper and yoke beingindependently movable and separable when the yoke is brought intoregister with 4the interruptions in the groove.

7. The combination `i--n a fitting of "the class described, of a wastestopper casing having an enlarged chamber, a waste stopper in saidcasing having an interrupted groove tor-med in its outer wall, stopperlifting means in said chamber engaging sai-d interrupted groove, andmeans extending vertically outside of said casing to .move saidoperating means and said stopper. Y
